IMPROVEMENT IN HOSE-NOZZLES.

Specification forming part of Letters Patent No. 198,515, dated December25, 1877; application iled June 11, 1877.

To all whom it may concern.-

Beit known that I, JOHN H. J onNsoN, of the city of Chicago, Cookcounty, State of Illinois, have invented a new and useful Improvement inHose-Nozzles, of which the following is a full description, referencebeing had to the accompanying drawings, in which- Figure 1 is anelevation, the main portion being shown in section; Fig. 2, an enlargedsection, with the plug removed; Fig. 3, a section at x x of Fig. 2,looking to the left. Figs. 4 and 5 show the plug in different positions;Fig. 6, a section at y of Fig. 4; Fig. 7, a section at z of Fig. 2.Figs. 2, 3, and 7 are enlarged.

This improvement relates to that class of hose-nozzles which are soconstructed that a solid stream can be thrown, and also so that, bychanging the position of the plug or cock, the water will escape fromthe nozzle in the form of a spray instead of a 'solid stream; and theinvention consists in the peculiar construction and arrangement ofrecesses and passages in the barrel, in combination with a three-wayplug, as hereinafter more fully described.

In the drawings, A represents the nozzle; B, the barrel which receivesthe plug or cock; a b, recesses in the barrel, upon opposite sidesthereof. c d are continuations of the recesses ab, and are, as shown, atright angles to a b. These passages e d do not open directly into thepassage through the nozzle, but open into the plug, which is providedwith openings, so arranged that the water can pass through the plug intothe main channel in the nozzle when the plug is in proper position. Thewall of the barrel extends across the passages c d, as shown at e, Fig.2. The wall at the end of the passage c is made straight, or nearlystraight, as shown at f, Fig. 7.

C is a three-way cock or plug, having a passage, g, through it, and alsoa passage, h, opening into the passage g. i, Fig. 1, shows the outletfrom the passage or chamber o to the main passage through the nozzle.There is a similar outlet from the passage g.

When the plug is in the position shown in Fig. 1, the passage gis inline with the passage through the nozzle, and the water will iiowthrough, emerging in a solid stream, as usual; but if the plug or cockbe turned so as to bring the opening h opposite to the inlet, the directow of the water through the nozzle will be cut off, and it will pass,first, through the opening h into the passage g through the plug orcock; and when the plug is in this position the water will pass into thetwo recesses a b, and through the passages c d, and, coming in contactwith the wall j', will be deiiected and thrown into the main passage,passing through it spirally, and emerging therefrom in the form of aspray.

The water can be entirely shut off by turning the plug, so that theportion opposite the Opening h will close the opening into the barrel.

I am aware that hose-nozzles have been made having two passages from thebarrel to the main channel, but not opening directly from the barrelinto the main channel. When so constructed these passages are liable tobecome filled up by obstructions passing through the water, which cannotbe easily removed. With my construction this cannot happen, for themoment the plug is removed the passages are all exposed to view.

The peculiar forms of the passages a b c d give to the water a spiralmovement, unaided by the form of the main channel or passages leadingfrom the barrel into such main chaunel.

What I claim as new, and desire to secure by Letters Patent, is-

In a hose-nozzle, the barrel B, provided with recesses a b and passagesc d, in combination with the three-way plug C, all constructed andoperating substantially as and for the purposes specified.

JOHN H. JOHNSON.
